Building the Business Case for SIP Trunking

In recent years, more and more businesses have decided to abandon traditional communications solutions, such as the PRI, in favor of SIP trunking.

While both techniques allow businesses to connect their existing phone systems to the cloud, SIP trunking has become the preferred telecommunications platform in a wide range of industries.

Why, you ask?

Truth be told, “why not” is probably the better question.  Many business owners choose SIP trunking over PRI because of cost savings, scalability, and disaster recovery options, just to name a few reasons.

Still, countless others are hesitant to make the switch.  And if you plan to be a SIP trunking advocate for your business, we recommend creating a strong business case for SIP trunking that outlines the following:

  • Your business’s existing (and future) communications needs
  • Any limitations or problems presented by your current communications setup
  • How much your business currently spends on communications
  • The ROI on a SIP trunking solution
  • The steps needed to ensure a smooth and secure deployment

In this article, we’ll show you how to cover all of these points (and more!) in 3 simple parts:

  1. Identifying Problems with Your Existing Communications Structure
  2. Recommending SIP Trunking as a Superior Solution
  3. Ensuring a Simple SIP Trunking Implementation

Developing the Business Case for SIP Trunking

Identifying Problems with Your Existing Communications System

The first section of your business case for SIP trunking should cover the problems or limitations of your current communications system. Here are a few examples of common limitations presented by using the PRI instead of SIP trunking:

Example 1: Underused phone company trunks

Traditional phone trunks come with 23 usable channels, or lines.  And whether you need to use all of them, or just a few, your business still pays for all 23 channels.

If you need to add a few more lines to account for new employees, you have to buy another trunk, which means you’ll have to pay more for additional unused lines.

Example 2: High long distance calling costs

Calls made or received over a data network typically cost far less than those made via the PSTN, or the incumbent phone company.  If your business makes a lot of long distance or international calls, you’re probably devoting a huge chunk of your budget to those communications needs.

Example 3: Separate networks for voice and data

Does your business have a network for all data uses, and another network for voice traffic only?  If so, you’re probably not taking advantage of the full potential of either one.

Since SIP trunking can be used to transmit both voice and data traffic, it allows you to make the most of one network.  (Plus, you’ll have one less throat to choke.)

In addition to listing and describing these types of limitations, you’ll also want to make sure that you highlight how much your current communications infrastructure costs your business.  That way, you’ll have the data to back up how much you could save by adopting a SIP trunking solution.

Recommending SIP Trunking as a Solution

In the next segment of your business case for SIP trunking, you’ll want to go over its costs, benefits and how, specifically, it will be a better alternative than your current situation.

If you’ve already done the research on the limitations of your current system, this part should be a breeze.  You’ll want to take all of the areas for improvement that you reviewed in the first section, and pair each one with a clear, business-focused explanation of how SIP trunking can help you overcome that obstacle.

You might find that it’s best to present this information in the form of a simple side-by-side comparison, much like the example below:

SIP Trunking vs On Premise Communications

Laying the Foundation for a Smooth Implementation

After you’ve provided your team with a complete overview of SIP trunking and its benefits, you’ll want to discuss how you plan to implement the new system.  You’ll also want to discuss any downtime you’d expect during the transition, how it will impact employees’ day to day interactions with the phone system, and how long it will take to be up and running.

This is also a good opportunity to address any potential concerns or reservations that your team might have about adopting a SIP trunking solution.

For example, many business owners are concerned (and rightfully so) about potential problems with voice quality.  If you expect questions about this subject, you’ll want to include information that explains how Quality of Service (QoS) settings can be used to ensure high call quality.

Visual aids can help you make a stronger point than an explanation alone.  As an example, we’ve included a short description of how Quality of Service settings work along with a simple diagram that illustrates the point.

In most cases, adequate bandwidth is enough to ensure high call quality with a SIP trunking solution. But if you do experience problems with delay, jitter, or packet loss, you can simply adjust the QoS settings on your router. Prioritizing voice packets over data packets provides the best possible call quality.

In the illustration below, you can see that the router is receiving data from telephones and other media devices. When QoS settings are configured properly, the router will place VoIP traffic in a specific, high priority queue that is processed before all other data. (See diagram below.)
